Do you think it is essential to do Sanchin with the jars (or other weighted objects) in order to develope the musculature to properly do the Sanchin kata?

Thanks for the interest in the body conditioning forum.
As far as the jars go I can only speculate for two reasons. One I have never used them only heard them discussed and two I am only 5 years into my Uechi training. I'm hoping GEM or some of the older, wiser and more talented in the Uechi community will jump in on this one.
I would like to speculate that the jars would not only help with muscular development of a persons core, forearms and back but might also aid is stance and posture development.
